Unmuted/Unswitched Inputs; Mono/Stereo Headsets - Garmin G1000 Pilot's Manual

DESCRIPTION
TRANSCEIVERS
The GMA 1347 handles three different transceivers:
• COM1 MIC
• COM2 MIC
• COM3 MIC
NOTE: A push-to-talk (PTT) switch must be
pressed to transmit on the selected radio.
Each audio panel can accept up to six (6) microphone
inputs, allowing for a two-person crew and up to four (4)
passenger intercom stations in the aircraft.

MONO/STEREO HEADSETS

The GMA 1347 can accommodate up to six (6) head-
sets, pilot, copilot and up to four (4) passengers.
NOTE: The use of stereo headsets is highly rec-
ommended.
Use of a monaural headset in a stereo jack shorts the
right headset channel output to ground. A person listen-
ing on a monaural headset hears only the left channel in
both ears. If a monaural headset is used at one of the pas-
senger positions, any other passenger listening on a stereo
headset hears audio in the left ear only, unless the headset
has a mono/stereo switch that is set to mono.
